Why is PVC Rigid resistant to Formaldehyde?
PVC Rigid shows good resistance to Formaldehyde due to its chlorinated structure providing resistance to acids, alkalis, and many inorganic chemicals.
⚠️ When NOT to use PVC Rigid
Avoid using PVC (Rigid) with ketones, esters, aromatic and chlorinated solvents. Maximum temperature around 60°C.
